Abstract

Amorf kopolymer av etylen og minst ett a-olefin, innholdende mellom 35 og 85 mol% etylenavledede enheter, og mellom 10 og 60 mol% a-olefin-avledede enheter. Kopolymeren har følgende kjennetegnende egenskaper: (A) innholdet i mol% av a-olefin i ko- polymeren (%a) og forholdet mellom den molare mengde a-olefin-diader og det molare innhold av a-olefin i kopolymeren (aa/a) tilfredsstiller følgende ligning: (%a) - 250 (aa/a) > 10 (B) mindre enn 2% av CH2-gruppene i polymerkjeden er i sekvenser (CH2)n, hvor n er et helt tall. Det beskrives også en fremgangsmåte for fremstilling av kopolymeren, omfattende polymerisering av etylen og ett eller flere a-olefiner, eventuelt også ett eller flere polyener, i nærvær av en spesiell katalysator omfattende omset- ningsproduktet av en metallocenforbin- delse og et alumoksan. Katalysatoren har to fluorenyl-grupper forbundet gjennom en brodannende gruppe.Amorphous copolymer of ethylene and at least one α-olefin, containing between 35 and 85 mol% ethylene-derived units, and between 10 and 60 mol% α-olefin-derived units. The copolymer has the following characteristic properties: (A) the content in mole% of α-olefin in the copolymer (% a) and the ratio of the molar amount of α-olefin dyads to the molar content of α-olefin in the copolymer (aa / a ) satisfies the following equation: (% a) - 250 (aa / a)> 10 (B) less than 2% of the CH 2 groups in the polymer chain are in sequences (CH 2) n, where n is an integer. Also disclosed is a process for preparing the copolymer comprising polymerization of ethylene and one or more α-olefins, optionally also one or more polyenes, in the presence of a special catalyst comprising the reaction product of a metallocene compound and an alumoxane. The catalyst has two fluorenyl groups connected through a bridging group.
